Jockscott,
I owned a pair of Eidolons for over 8 years, and found they rewarded you for using high performance cables (fabulous speakers, by the way). The best pairing I found - hands down - was Siltech The Emperor. However, I understand that may be a bit on the expensive side. I also had success with Purist Dominus and Kubala Emotion. At a more bargain price, I would recommend Wywires.
I would not use them with Cardas cables; for example, I tried Golden Reference and was very disappointed with the plummy bass and softened dynamics. In fact, I would not recommend them with any of the cable brands you listed (unless you would spring for Nordost Odin).
Finally, regarding demos, there is always the Cable Company (http://www.thecableco.com/), who for a reasonable fee will ship out multiple cables for you to demo.
Best of luck.
